Hand eczema is a chronic disease that results in economic and psychosocial burdens. The aim of this study was to systematically review and assess the magnitude of the association between exposure related to occupations and the incidence rate of hand eczema. A systematic search in PubMed, EMBASE, CINAHL and Cochrane databases, from inception to September 2017, of full-text observational studies rep

Rel stringent factors are bifunctional ribosome-associated enzymes that catalyze both synthesis and hydrolysis of the alarmones (p)ppGpp. Besides the allosteric control by starved ribosomes and (p)ppGpp, Rel is regulated by various protein factors depending on specific stress conditions, including the c-di-AMP-binding protein DarB. However, how these effector proteins control Rel remains unknown.

Sedan antiken har humanismen försökt definiera den mänskliga naturens väsen samtidigt som den placerar människan i universums centrum som ”alla tings mått”. I ett försök att omvärdera människans betydelse har det talats om ett slags transhumanistisk intersubjektivitet. Jag utgår från fysikern och feministen Karen Barads begrepp intraaktion (samspel mellan integrerade delar). Barad myntar begreppet

The first edition of Astrid Lindgren's book Pippi Langstrumpf (GDR/1975) is our starting point for this presentation. It is also our first joint presentation of our project “Pippi beyond the border” (The Foundation for Baltic and East European Studies). The aim of the project is to examine the complex reception history of Astrid Lindgren's classic children's book Pippi Longstocking in the GDR, whi

Cerium oxide nanoparticles modified montmorillonite was obtained by interaction of a clay with (NH4)2Ce(NO3)6. The mean size of cerium oxide nanoparticles in clay was at 3.5 nm. The product was an amorphous solid and showed high permanent porosity and stability at high temperatures. The amorphous structure of the sample was proven by X-ray diffraction and electronic diffraction. The porous structu

Pippi lutar sig ut ur en grön inramning på en skiss som Ingrid Vang Nyman tecknade till den första boken om Pippi. Vid en jämförelse med den pärmbild som trycktes kan skissens djupverkan överaska. Som man förväntar sig av den rebelliska figur som uppträder i boken, tycks Pippi dessutom ha rivit sönder den grön yta som likt en pappersridå skiljer henne från betraktaren. En förklaring till att skiss

The spectral characteristics in the visible range of synthesized nanocomposites based on cadmium sulfide and ultradispersed polytetrafluoroethylene are investigated experimentally. Local perturbations are found in the long-wavelength regions of the reflection and absorption spectra, which are related to the optical transitions between the critical points of the valence and conduction bands of the

The spectral characteristics of absorption and photoluminescence of synthetic composite materials based on cadmium sulfide nanoparticles and polyethylene are studied in the visible and near-IR wavelength ranges. It is shown that the quantum efficiency of a material with CdS nanoparticles about 6 nm in size in a matrix of high-pressure polyethylene is the highest. The estimation of the photolumines

Cobalt-containing nanoparticles have been prepared via thermal decomposition of cobalt acetate on the surface of poly(tetrafluoroethylene) (PTFE) microgranules forming a fluidized bed over the surface of hot mineral oil. Using transmission electron microscopy, the average size of the cobalt-containing nanoparticles has been determined to be 3.6 nm. The composition and structure of the nanoparticle

We have prepared nanomaterials consisting of SiO 2 microgranules and Fe-containing nanoparticles on their surface and determined the size and composition of the nanoparticles. The nanoparticles are shown to have a core-shell structure (α-Fe core and γ-Fe 2O 3 shell). The α-Fe core and Fe 2O 3 shell are responsible, respectively, for the broad and narrow lines in the EMR spectrum of the nanoparticl

Nanosized copper-containing particles stabilized on the surface of polymer nanograins were obtained by thermal decomposition of copper-containing precursors in a fluidized bed of ultradispersed polytetrafluoroethylene. Transmission electron microscopy showed that the average size of nanoparticles is 10-12 nm. The structure of the particles was determined by EXAFS, EPR, and X-ray powder diffraction

In this work we demonstrate that it is possible to create new magnetic material based on metal-containing nanoparticles stabilized on the surface of polytetrafluoroethylene nanogranules. Magnetic properties of these materials have been investigated. The materials were prepared by a method of thermal decomposition of metal-containing compounds in the heated polytetrafluoroethylene-oil system. Trans

Nanoparticles of Fe1-xMnx (0.07 < x < 0.20) alloys are studied using electron magnetic resonance in the temperature range 295-500 K. It is found that the temperature and manganese concentration in the nanoparticles have a noticeable effect on their electron magnetic resonance spectra. It is suggested that the Fe1-xMnx nanoparticles contain phases with different magnetic properties and that the rel

Nanocomposites of high-pressure polyethylene and zinc oxide nanoparticles are synthesized through thermal decomposition of zinc acetate. The phase composition of the nanocomposites is determined by x-ray diffraction (XRD), and the average size of ZnO nanoparticles is evaluated by transmission electron microscopy. The average size of the nanoparticles varies from 1 to 10 nm, depending on the ZnO co

The aim of this presentation is to examine the complex reception history of Astrid Lindgren's classic children's book “Pippi Longstocking” in the GDR based on the appearance and paper quality of the various editions. “Pippi Longstockning” was published in two different editions in 1975 and 1988 by the East Berlin Children's Book Publishing House (Kinderbuchverlag Berlin). The differences between t
